I am trying the examples in www.xmlrpc.com with twisted matrix but I have hit a wall I hope that somebody can give me a hand.
I am trying to call the method from my xml ...
My xml code :
<?xml version="1.0"?>
<methodCall>
<methodName>examples.tryone.Echoer.echo_something</methodName>
<params>
<param>
<value>Name</value>
</param>
</params>
</methodCall>
My xmlrpc server code :
#!c:\python22\python.exe
from twisted.web import xmlrpc
from twisted.internet import defer
import xmlrpclib
class Echoer(xmlrpc.XMLRPC):
def echo_something(self,name):
return name
def main():
from twisted.internet.app import Application
from twisted.web import server
app = Application("xmlrpc")
r = Echoer()
app.listenTCP(7080, server.Site(r))
app.run(0)
if __name__ == '__main__':
main()
The error I get :
web.Server Traceback xml.parsers.expat.ExpatError: no element found: line 1, column 0
I a newbie at this so please forgive me if what i am doing is like really stupid or i am asking a dumb question. Thanks

I'm in the process of adapting Lore for the documentation on my project.
I've subclassed it, and attached my work.
I decided not to do this as a patch after all; the changes should be very
easy to drop into the lore core if this turns out to be useful.
What do this script and module do?
* Convert lore-html to latex (like html2latex and latex.py)
What does it do differently (see Advantages for the reasons why)?
1) Images are converted to png instead of eps before for use in the
\includegraphics command. (Images that start as png are unchanged.)
2) Images are automatically formatted to 6.5in wide, maintaining aspect
ratio.
What are the advantages?
1) Works anywhere PIL is available / eliminates dependency on pngtopnm
2) Because PIL supports so many formats, the subclass now supports a
boatload of image formats instead of just png.
3) Resulting image quality is better, although it can still improve more.
4) Images don't flow outside the margins
Notes on Image Quality: I achieved the best quality by converting my
.dia's to .eps and including .eps directly. Since these are vector
graphics, the quality is perfect, to the resolution of the pdf itself; but
when I did it this way, the fonts in the diagrams were mapped to different
fonts that overflowed their boxes and made the diagram unreadable. Next
best was to convert dia=>eps=>png (using ImageMagick's convert utility in
the shell) then including the png. This could improve if I could figure
out how to make includegraphics use a sensible DPI when it does its
conversion to dvi. Worst was dia=>eps=>png=>eps, for reasons that are
not obvious to me. Both png and eps are non-lossy, so the last two
conversion paths should have equal quality, but they don't.
What isn't right yet?
1) visitNode_img() always uses png as the target extension, and
2) convert_any() assumes this. convert_any() will fail for certain target
image formats because the mode ("""im.convert('RGB')...""") has to match
the target format. This can be fixed with a simple exception handler
(TODO).
3) Images should be formatted to a width of
(pagewidth-leftmargin-rightmagin), instead of a hardcoded 6.5in (which
assumes, among other things, letter-sized paper). I'm not latex guru
enough to make this work yet.
Other notes:
It looks like the .eps in Twisted doc isn't being generated from dia
during process-docs. This is very easy to do in batch, even without an X
server; ask me if anyone wants to see my mklore script.

I'm working on a SSH client/server for Twisted,
and some of the things the client needs to work
with are passwords both for login and for private
keys, and then the decrypted keys. Obviously,
storing these in memory leads to the possibility
of acessing them and thereby compromising the
user. Is there a way to overwrite the data, or
otherwise erase it from memory?

How do I stay informed about changes to the repository?
How can I keep a checked-out working copy up to date?
How can I keep a back-up of my repository off site?
. . .
Twisted Matrix Laboratories has been using CVSToys to keep track of
their CVS repository for the past year, and now CVSToys is being
released to the general public for the first time.
FreshCVS ("the biggest best and only toy we've got"), working in
conjunction with CVS's 'loginfo' hook, will perform actions in response
to a commit. Unlike 'loginfo' alone, which will only execute the first
matching command it finds, FreshCVS's flexible configuration allows for
any number of actions to take place. Actions include notification by
mail (with diffs), chat service, and web (both HTML and RSS), updating a
working copy, and rsync to backup.
Another key feature of FreshCVS notifications is that you receive
one per commit, not one for each directory of the commit as
loginfo-triggered scripts are prone to do.
FreshCVS is extensible with Python, and you may also publish
notifications by a Perspective Broker network service, allowing 3rd
party clients to listen in.
More information and downloads may be found at
http://purl.net/net/CVSToys
CVSToys is open source software.
Share and enjoy,

This makes no sense. The Twisted version has nothing to do with the
version of usage.Options-using applications.

I've just discovered some unfortunate behavior when dirdbm and rebuild are
combined (as I have recently combined them in Pynfo). It is easily
duplicated:
from twisted.persisted import dirdbm
from twisted.python import rebuild
s = dirdbm.Shelf('dirdbm.rebuild.test')
s['key'] = 'value'
rebuild.rebuild(dirdbm)
print s['key']
Investigating with pdb, I discovered:
> /home/exarkun/projects/python/Twisted/twisted/persisted/dirdbm.py(90)_readFile()
-> f = _open(path, "rb")
(Pdb) next
OSError: (17, 'File exists', '/home/exarkun/test/dirdbm.rebuild.test/a2V5_')
I don't really know where to go from here. Does anyone have any ideas?

Hi,
What's the prefered way to use distutils to package a twisted plugin.
The key question being, how do you install the plugins.tml file ? Is
there any distutils extensions available ?
